MACHINE FOR MAKING PAPER FILLERS.

Application filed March 12, 1927. Serial No. 174,841.

This improvement relates to a machine for making paper fillers for use in various kinds of devices including moulding devices, such as those described in Letters Patent to Bolender and Creamer $1,387,639.

In a general way the machine is adapted to operate upon a sheet of paper, preferably Japanese crepe paper, and mechanism is provided for compressing the side edges of the paper towards its central line of travel thereby forming folds in the paper. This paper having a coating of adhesive substance will be readily thereafter compressed into such shape and the folds will be held compactly together forming a tape or tube which can be twisted and turned into various shapes and positions without diiiiculty' The tube itself is described in a copending application of Bolender and Creamer filed February 5th, 1927, Serial No; 166,123.

Other objects and advantages will be in part indicated in the following description and in part rendered apparent therefrom in connection with the annexed drawings.

To enable others skilled in the art so fully to apprehend the underlying features hereof that they may embody the same in the various ways contemplated by this invention, drawings depicting a preferred typical construction have been annexed as a part of this disclosure and, in such drawings, like char acters of reference denote corresponding parts throughout all the views, of which:

Figure 1 is a side elevation of the machine. Fig. 2 is a plan view. Fig. 8 is an elevation of the feed and creasing rolls. Fig. 4 is a sectional view taken on the line of Fig. 1. Fig. 5 is a viewtaken on the line 5-5 of Fig. 1. Figs. 6 and 7 are detail views of the worm gear mechanism for operating the disk. Figs. 8 and 9 are detail views of the adjusting device for one of the shafts. Fig. 10 is an elevational view taken from one side of Fig. 2, i. e. the top part of that figure. Fig. 11 is a diagrammatic view ofthe sheet of paper showing the pleats or crimps.

The base of the machine is indicated by l, on which is mounted the supporting frame 2, formed with guide-ways 2 thereon, which are associated with thesliding memhers 3 and these sliding members :3 support the operating device for folding the paper sheet. These heads 3 are shown slidably mounted in Figs. 1 and 2. There is a nut or together or be separated, thereby providing the adjustment for the passageway for the sheet of paper There is an operating shaftt associated with each head (see Figs. 1 and 6) and this shaft 7 is supported in bearings at its upper and lower ends as more fully explained hereinafter. This operating shaft has secured thereon a worm-wheel 9 which is in mesh with av worm 10. Inorder to permit the heads 3 to be moved outwardly or nwardly the worms 10 are keyed to the drivmg shaft 11 and there is aiyoke 12 for connecting the shafts 7 and 11 in a way to insure the gear and worm remaining in proper mesh when the shaft 7 is moved or tilted as will be hereinafter explained. This yoke 12 (see Fig. 7 is. loosely mounted on the shaft 7 and is formed with bearings which extend around the worm shaft 11 (see Fig. 6); The pairs of disks marked 13 and 14c are the instrumentalities for forming the folds in the paper and. these disks are mounted on the shafts 7. there being a disk for each shaft. These disks 13 and 14 are formed with hub portions 13* and 14 projecting from the center of the disks and the disks are so mounted that the disks themselves will overlap and the hub portions will lie in proximity one to theother so as to form a passageway marked 16 (see Fig. 2). It is desirable to tilt one of the diskspreferably the lower disk, (see Fig. 1) so that the exit of the passageway will present a freedom for the movement of the folded paper after it has been operated on by the hubs of thetwo disks, itbeing understood that one disk has the hub on its upper surface, and theother disk has the hub on its lower surface. In order to enable one of the disks to be tilted the set screws 15 are employed (see Figs. 1, 8 and 9) so that by adjusting the set screws the shaft 7 can be slightly tilted which will cause the disk supported thereby to be tilted and during its movement the gear 9 and worm 10 will be kept properly in mesh by the yoke structure indicatedby 12. There is a stationary guide 17 (Fig. 2) which extends in close proximity to the periphery of the disks 13 and 14 and the sheet of paper is thereby guided into the proper path to insure its entering the passageway 16 in such a manner that the edges of the hubs of the two disks can compress the side edges of the sheet of paper toward the central line thereof thereby forming a multiplicity of small folds and when the hubs 1- and 14 are acting upon this sheet of paper the paper is also held against displacement by the flat surface of the disks 13 and 14. As these disks are rotated in the direction indicated by the arrows (Fig. 2) this passageway is in effect formed by four movable walls, two of which are the flat surfaces of the disks and two the surfaces of the hubs. The motor shaft 18 (Figs. 1 and 2) is properly supported by sub-base 1 of the machine and this motor shaft has secured to its outer end a worm '19 which is meshed with the worm-wheel 20 secured to one end of the driving shaft 11 thereby the motion is transmitted through said shaft to the worms 10 and the worm wheels 9 herebefore referred to. This motor shaft has also a worm 21 secured thereto intermediate its ends which is in mesh with a worm-wheel 22 mounted on one end of a cross shaft 522 which is supported by the sub-base 1 This cross shaft 22 carries the upper roll 23 hereinafter referred to and at its opposite end is geared to the lower roller shaft 22 which carries the roll 24. These rolls are indicated by 23 and 24 and are what are termed the forming rolls. One roll has an annular groove and the other a tongue projection thereby giving to the paper filler the desirable form for its use in mouldings hereinbefore referred to. The cross shaft 22 has on its extreme end a disk 28 and on the flat surface of that disk there is preferably a fibre disk 29 which engages that surface. This fibre disk 29 is slidably mounted on the shaft 31 which shaft in turn is supported in bearings that are in turn supported by the bracket 1 (Fig. 10). A screw 31 passes through the yoke 30 which is con- 'nected to the fibre disk 29 and by turning this screw 31 the fibre disk will be adjusted to transmit the necessary movement to the shaft 31. This shaft 31 has at its opposite end (Fig. 2) p a worm 32 which is in mesh with a worm-wheel 33 which is secured to a cross shaft and at the opposite end of this cross shaft there is a gear 34 which is in mesh with a gear- 35 secured to an upper roller shaft. As indicated in Fig. 3 the lower roller shaft carrying the gear 34 and the upper shaft carrying the gear 35 have near the center thereof two rolls which are formed preferably to crease the paper. The small ridges formed in these rollsaecomplish that purpose but it is not essential to the operation of the machine that these ridges be employed. These rolls also feed thepaper sheet to the passageway 16 and the machine is so geared that these rolls will operate at a slightly faster rate than the disks 13 and 14 so as to prevent the paper sheet from being unduly stretched when the edges of the paper sheet come in contact with the hub portions hcrebefore referred to and forming rolls 23 and 24 are geared so that these rolls will operate slightly faster than the above mentioned rolls to insure the paper sheet passing through the passageway 11'; without being buckled or barred.

From the foregoing description it will be clear that the paper sheet preferably creased slightly by the creasing rolls and likewise fed by them through the guide 17 to a point where the hubs of the disks 13 and 14: will begin to operate upon the paper sheet and when the sheet reaches the narrowest portion of the mssageway the folds will be formed and the folded article will be properly held in that passageway, and the folds will be inclined to be held together by the adhesive substance which is applied to the sheet of paper prior to it being fed into the machine and this folded sheet will then pass into the groove formed in one of the rollers 23 or and these rollers will then complete the feeding of the article while noting upon the folded sheet to give it a contour such as described clearly in the copending application heretofore referred to. As heretofore explained these two disks 13 and 14 are slidably mounted so that the necessary variation in the width of the passage can be made by operating the hand-wheel (i and the proper clearance n'lay be obtained by tilting one of the shafts 7 and when this is done there is minimized the danger of the article adhering to the face of the disk and thereby tending to throw the article out. of the proper path of movement necessary to reach the groove formed in one of the forming rolls. Nothing herein is intended to waive any of the patentable features of the copending application Serial No. 163.123.

lVithout further analysis, the foregoing will so fully reveal the gist of this invtmtion that others can, by applying current knowledge, readily adapt it for various utilizations by retaining one or more of the features, that, from the standpoint of the prior art, fairly constitute essential charactcristics of either the generic or specific aspects of this invention and. therefore, such adaptations should be, and are intended to be, comprehended within the meaning and range of equivalency of the following claims:
